The present invention relates to a disintegrating device for grinding fiber pulp material such as wood chips in the gap between said discs.
In modern disintegrators, the disks rotate at high speeds and have large diameters, which means that the centrifugal forces acting on the grinding plates are significantly stronger. For example, a centrifugal force of about 50 tons acts on a grinding plate of several tons.

る。 Conventional grinding plates are secured to the supporting disk by bolts that are screwed into the grinding plate from behind. Since extremely high stresses have to be taken into account, several bolts are used to attach each grinding plate, but nevertheless the stresses created in the grinding plate itself are large and
The grinding plate must be designed to have a thickness and thus weight that is significantly greater than is actually necessary to provide ribs and ridges on its surface. In addition to this, in order to make the grinding plate as resistant to wear as possible, it must be made of a very hard material, the strength of which cannot be easily estimated by set-up calculations. In other words, the design dimensions of the grinding plates become extremely large, which further increases the stresses on these grinding plates and the bolts that attach them to the disks, causing the grinding Because the plate is so thick, the centrifugal force applied to it creates a strong torque around its circumference, tending to throw the grinding plate outward from the disk.

(b) a dovetail groove extending into a narrower width is formed in the disk; (c) A tongue-shaped portion having a complementary shape to the dovetail groove is provided on the surface of the grinding plate opposite to the grinding surface in order to firmly wedge the disk; In order to hold the tongue in its wedged position in the dovetail groove and to prevent the grinding plate from being thrown out of that position due to centrifugal force, a removable annular member is attached to the tongue. disposed about the periphery of the disk so as to engage the shaped portion.

る。 According to the present invention, the tongue-shaped portion is provided on the grinding plate, and a dovetail groove into which the tongue-shaped portion is fitted is formed in the disk supporting the grinding plate, so that the grinding plate is in close contact with the disk. The surface of the plate can be significantly larger than when using bolts, thus providing a better distribution of stress across the grinding plate. As a result, the part of the grinding plate behind the dovetailed area can be made considerably thinner than before, which reduces the action of centrifugal forces and thus reduces the grinding plate in close contact with the disk. The stresses occurring in the plane of the plate are likewise reduced. Another advantage of employing this invention is that the surface of the grinding plate can have deep grooves for forming ribs and ridges. The length of time it takes for a grinding plate to wear out to the point that it needs to be replaced is highly dependent on the height of the ribs and ridges, so the deep grooves described above allow for the use of the plate. The length of time increases. Furthermore, the width of the dovetail groove in the disk gradually becomes narrower toward the radial inward side of the disk, and the tongue-shaped portion in the grinding plate has a shape complementary to the dovetail groove, so that the grinding plate has a shape that is complementary to the dovetail groove. Just push it into the disc from the outside in the radial direction and it will tighten firmly against the disc. Moreover, since the annular member that engages with the tongue is disposed around the circumference of the disc, the grinding plate is kept clamped to the disc even when the disc rotates.

4 and 26 widen toward the bottom surface of the dovetail groove 22, and the width of the groove 22 gradually becomes smaller inward in the radial direction. This wedge ratio can be in the 1:20 range. A similar dovetail groove 28 with sloped side walls 30, 32 is provided in the disc 10 for the guide plate 19. In particular, as is clear from FIG.
The surface opposite the grinding surface with 6 is provided with a tongue or protrusion 34 which can be inserted into the dovetail groove 22.
It has a complementary shape and has the same dimensions and ratios. The guide plate 19 has a dovetail groove 28
It is provided with a tongue-shaped portion 35 (FIG. 3) that fits into the.

The grinding plate 12 and the guide plate 19 are installed by being introduced from the outer circumference of the disc 10 into dovetail grooves 22 and 28, respectively, and these tongues 3
4 and 35 are pushed into such a position that they achieve a tight connection without play with the dovetail groove. To hold the grinding plate 12 in position very reliably, a removable annular member 36 (FIG. 3) is mounted around the circumference of the disc 10 and attached to the tongue 3.
4. This annular member 36 is fixed to the disc 10, for example by a threaded connection member (not shown), and extends to the same extent as the outer projection 38 of the grinding plate 12. As a result, the grinding plate 12 and its inner guide plate 19 are fixed radially very firmly against the effects of centrifugal forces caused by rotation of the disk.

する。 Therefore, according to the invention, the area between the grinding plate and the guide plate and the disc that connects them can be a large part of the common surface, for example, more than 50%, so that in the grinding plate and the guide plate, The radial length of the tongue and the dovetail groove of the disk engaging it can be greater than half the radial dimension of these grinding plates and guide plates, so that the stresses resulting from the centrifugal force are It is distributed over the entire grinding plate and guide plate, rather than being concentrated at only a few points, as is the case with conventionally used bolted connections. Despite the fact that these plates are made of hard materials in order to provide resistance to the very significant wear that occurs during grinding, they are substantially thinner and therefore lighter than before due to the dovetail joints. This also serves to further reduce the stresses occurring, especially in the grinding plate and the guide plate. By fitting the tongues 34, 35 into the disk 10, the centers of gravity of the grinding plate and the guide plate move toward the disk, so that the annular shape due to the action of centrifugal force The tilting moments of these plates about member 36 are significantly reduced.

装置。[Claims] 1. It has two discs that face each other and rotate relative to each other,
the disc has a central opening for introducing material into a central infeed zone and supports a number of arc-shaped grinding plates, the grinding plates being arranged annularly along the disk; and extending radially inwardly from the periphery of the disc toward the infeed zone, the attrition plate further comprising a attrition zone having a attrition surface with ribs and ridges. A disintegrating device for grinding fibrous pulp material, such as wood chips, in the interstices between discs, comprising: (a) tapering in width from an outer circumferential portion of said discs towards a radially inner portion of said discs; a dovetail groove is formed in the disk, extending so as to: (b) firmly holding the grinding plate against the disk by pressing the grinding plate towards the center of the disk; In order to wedge the disc, a tongue-shaped portion having a complementary shape to the dovetail groove is provided on a surface of the grinding plate opposite to the grinding surface, and (c) when the disk rotates, A removable annular member engages the tongue to hold the tongue in its wedged position in the dovetail groove and to prevent centrifugal force from throwing the grinding plate out of that position. The disintegration device is arranged around the periphery of the disc so as to fit together. 2 the attrition zone is located in a radially outer portion of the attrition plate, and the radially inner portion of the attrition plate is provided with a feed for conveying material from the infeed zone to the attrition zone; A disintegration device according to claim 1, which constitutes a zone. 3. Radially inwardly of the grinding plate, a guide plate constituting a feed zone for feeding material from the feed zone to the grinding zone is arranged annularly along the disk and is dovetailed. The disaggregation device according to claim 1, which is attached to the disk with a.
